Fever by Maya Banks

Jace, Ash, and Gabe: three of the wealthiest, most powerful men in the country. They're accustomed to getting anything they want. Anything at all. For Jace, it's a woman whose allure takes him completely by surprise... Jace Crestwell, Ash McIntyre, and Gabe Hamilton have been best friends and successful business partners for years. They're powerful, they're imposing, they're irresistibly sexy, and Jace and Ash share everything-including their women. When they meet Bethany, Jace begins to feel things he's never experienced before: jealousy, and a powerful obsession that threatens him, overwhelms him-and excites him beyond control. Jace isn't sharing Bethany-with anyone. He's determined to be the only man in her life, and it's jeopardizing a lifelong friendship with Ash. Bethany will be his and his alone...even if it means turning his back on his best friend.
